Christie Digital WX7K-M — buyer FAQs
What is the Christie Digital WX7K-M and what projection technology does it use?
The Christie Digital WX7K-M is a compact 3-chip DLP digital projector built around a 0.85-inch DMD at WXGA resolution (1366 x 768). It uses dual 200W Osram P-VIP mercury lamps to deliver 6,270 centre lumens in dual-lamp mode, dropping to 3,135 centre lumens when running a single lamp. A dynamic iris delivers contrast of up to 10,000:1, with 650:1 ANSI contrast as a typical figure.
What built-in processing and image management features does the WX7K-M include?
The WX7K-M includes Christie Twist image warping and edge-blending, Comprehensive Color Adjustment, and an Intelligent Lens System covering zoom, focus, and horizontal and vertical lens offset. It also supports multi-windowing and screen processing in configurations up to a 3x3 array, and has built-in portrait display capabilities. The chassis is dust-sealed and filter-free, removing the need for regular filter maintenance.
How does the WX7K-M manage power and heat during operation?
At full brightness the WX7K-M draws a maximum of 870W. Thermal feedback systems automatically adjust the number of lamps in use and their power level, control fan speed to cool the projector, and can shut the unit down if no signal is received. Running in eco mode extends lamp life from 2,000 hours up to 3,000 hours per lamp set.
Who makes the WX7K-M and where does it sit in their projector range?
The WX7K-M is made by Christie Digital Systems, a visual display technologies company headquartered in Cypress, California, with engineering in Kitchener, Ontario, Canada. Christie is known for digital projection spanning cinema and large-venue applications as well as professional AV. The WX7K-M sits in the professional installation segment, described as having the smallest chassis in its class for a dual-lamp WXGA 3-chip DLP projector of this output.
What should I check when buying a used Christie WX7K-M?
Lamp hours are the primary consideration on a second-hand WX7K-M, as each dual 200W lamp set has a rated life of 2,000 hours (up to 3,000 in eco mode), so remaining hours directly affect running costs. Confirm both lamps are present and functional, check the dust-sealed engine for any damage, and verify the Intelligent Lens System operates correctly. Used units on 10K Used carry a 21-day warranty covering major functional faults; full buying detail is at https://www.10kused.com/used-av-equipment-guide/.
